録請求の範囲第１項記載の圧電型摩擦ブレーキ。[Claims for Utility Model Registration] 1. A friction member that is attached to and interlocks with a controlled object, a pressing member that presses the friction member to generate frictional force, and means for pressing the pressing member against the friction member. and a means for pushing back the pressing member to remove the frictional force, at least one of the means for pressing the pressing member against the frictional member and the means for pushing back the pressing member to remove the frictional force. An actuator constructed using a piezoelectric ceramic element is used on one side; a displacement magnifying lever is provided using a lever to increase the displacement amount due to the electric stress of the actuator; and the piezoelectric ceramic element is attached to both ends in the direction of expansion and contraction. A piezoelectric friction type friction device, characterized in that an element base is provided which is clamped and supported from the surface by clamping members, and the clamping member of the element base is separated in advance so that the element can be clamped and fixed to the element base, and is attached later. brake. 2. The piezoelectric friction brake according to claim 1, wherein a part of the element-based clamping member is the displacement magnifying lever.
